Sienna black computer Chair.

We live in a high rise and the delivery was on time and taken up in the lift and delivered to our unit, so I had no need to struggle with the heavy package. The chair was easy to assemble and is very comfortable with good lumbar support. Great value for money and "Just Office Chairs" was very easy to deal with online. The chair cost me $158.00 and delivery was free. For anyone looking for an office chair online at a reasonable price, I would have no hesitation in recommending this company.
